MEDICINE-DROPPER.

Specification of Letters Patent.

Application filed May 14, 1912. Serial No. 697,227.

Patented Mar. 4, 191 3.

To all whom it may concern:

Be it known that I, CHARLES F. I'IYDE, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have. invented a new and Improved Medicine-Dropper, of which thefollowing is a full, clear, and exact description.

This invention relates to dropper-s for liquids, and especially tobottles adapted to contain medicines from which the same may be droppedeasily and accurately.

The object of the invention is to provide a bottle of the special natureindicated which is more efiective for its purpose than those commonlyemployed and which will be substantially airtight when not in use as adropper so that the contents of the bottle will be properly preserved.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaim.

Reference is to be had to the accompany; ing drawings forming a part ofthis specification in which like characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is avertical face view of the bottle made in accordance witha preferredembodiment of this invention; Fig. 2 is a verticalsection through theneck of the bottle substantially on the line 22 of Flg. 1; and Fig. 3 isa similar view with the movable parts in a different position.

Referring particularly to the drawings, I have shown at 10 any suitableform or size of a container for liquids, hereinafter referred to as abottle, but which obviously may be a ju or some other speclfic type ofcontainer. gaid bottle is shown provided with a neck 11 adapted to beclosed. by a cork 12 in the usual manner.

The interior surface of the neck 11, adjacent the mouth, is formed wltha long1tudinal roove 13 through which, when the bottle is tilted, themed cine may be caused or permitted to flow in drops. Topermlt thisaction the stopper may be withdrawn slightly if it had been previouslyforced so deeply into the neck as to make the bottle air-tight. Tofacilitate the flow of the liquid through the groove 13, the stopper 12ma be formed with a companion groove 14 which may be caused to registerwith the bottle groove as indicated in Fig. 2. Whether or not the stoper must be specially formed as indicated will of course, depend upon theviscosity of the liquid or the rate at which it is to be delivered fromthe bottle.

On the side of the'neck .11 opposite the groove 13 is formed an externallongitudinal rib 15 which merges into the rim 16 surrounding the mouthof the bottle. Said rib 15 serves to reinforce the bottle neck and toprovide a substantial base for a comparatively long inclined vent 17extending entirely through the wall of the neck, the inclination of saidvent being down toward the inside of the bottle. The purpose-of thisvent 17 is to admit air during the operation of dropping medicine or thelike from the bottle through the groove 13, as described above. dropper,I prefer, to seal the vent 17 by means of a flat elastic band 18surrounding the neck of the bottle and adapted to' slip over the outerend of said vent, as shown in Fig. 3, the band, however, being adaptedto be slipped up-or down so as to open the vent as may be required. Whenthe band is moved away from the vent, the admission of air may becontrolled more or less, as desired, by the operators thumb or finger,the form of the neck with respect to the rib facilitating such action ofthe operator.

I wish it to be understood that I am not to be limited to any particularmaterials, or relative sizes and proportions of the parts or features ofthis invention, reserving the right to vary from those shown to aconsid- \Vhen the bottle is not used as a 1 erable extent withoutdeparting from the spirit of the invention.

' Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

In a medicine dropper, the combination with a bottle having a neckprovided with a longitudinal groove along its inner surface adjacent themouth, a longitudinal rib on the outside of the neck opposite saidgroove, and a downwardly and inwardly in.-

clined vent extending through said. rib and neck, offlmeans slid'able upand down on the 5 neck and rib to seal' said vent, substantially assetforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscrlbing witnesses.
